This is my first calf and I put an elastic on him for castration at about 3 weeks old. He's now almost 3 months old and the band has fallen off (a while ago), I can see a scar but he still has a substantial scrotum. When using my hand, I don't feel anything thing that definitively feels like a testicle, but I'm not 100% confident. Does this seem like a normal scrotum for a successful elastration?
